Question about the mood

I can't answer the subjective/indicative question, but I feel obliged to point out that these sentences:

Seoul BrotherAs I am not a butterfly, I don't have wings.As I am not a butterfyl, I cannot(will not) have wings.

are not logical. Birds, airplanes, and moths are not butterflies, and yet they all have wings.

“If I were a butterfly, I would have wings.”
(This establishes that without wings I cannot be a butterfly. If instead I were a wasp, I would still have wings; so if I am not a butterfly (but I am a wasp), I can still have wings.)
“Since I do not have wings, I am not a butterfly.”
The other two suggested sentences are not correct.

thanks for your advice. The subjective in the sentence is human.

Understood. Regardless, you wanted to change the mood of the sentence and all you have to work with is “If I were a butterfly, I would have wings.”
So, without wings, I am not a butterfly.

Thanks for your advice. I have one more question. How about the sentence? If I were a boy even just for day, I would roll out of bed in the morning and throw on what I wanted and go. How can I turn it into the indicative mood? thanks in advance.

Seoul BrotherBelow is the sentence written in a subjunctive mood.

No, only the if-clause is subjunctive mood.
The main clause is indicative mood.

You cannot change it without changing the meaning.
